Load parameters are used to describe all types of standards except a Through, a Sliding Match, a Line
and an Attenuation.
 The Through standard is a through-connection between two ports with minimum loss which is
taken into account by the Offset Parameters.
 The Sliding Match is a one-port standard with variable load parameters (sliding load), so there is
no fixed load model.
 The Line standard is a line of variable length with minimum loss which is taken into account by the
Offset Parameters.
 The Attenuation is a two-port standard which is fully matched in both directions (the reflection
factor at both ports is zero). No load and offset parameters need to be set.

Waveguide Calibration Kits
Rohde & Schwarz offers special waveguide calibration kits for test setups involving frequency converters.
 Calibration Kit R&S ZV-WR10 is suited for the frequency converter R&S ZVA-Z110(E) (frequency
range: 75 GHz to 110 GHz)
